Package kmidimon

https://kmidimon.sourceforge.net

Drumstick MIDI Monitor monitors events coming from MIDI external ports or
applications via the ALSA sequencer, and from SMF (Standard MIDI files) or
WRK (Cakewalk/Sonar) files. It is especially useful if you want to debug MIDI
software or your MIDI setup. It features a nice graphical user interface,
customizable event filters and sequencer parameters, support for MIDI and ALSA
messages, and saving the recorded event list to a SMF or text file.
